BRAIDING CARRIER.

Application led January 5, 1927. Serial No. 159,053.

My `invention relates tobraiding carriers 'whicheinploy a pawl-controlled bobbin; and it consists in vimproved thread tensioning means mounted upon the base portion of the Vcarrier and comprising a thread-operated tensioning lever and a bobbin-releasing pawl leverv cooperatively arranged, as' fully set forth in connectionwith' the accompanying drawings, the novel rfeatures being clearly defined in the subjoined claims. i 1' Fig. lis a front Aview of a carrier embodying my invention;y thev bobbin spindle being partially broken away and the ratchet wheel shown in cross-section, and a filled bobbiny being indicated in dotted outline.

Fig. 2 is a side view looking int-he direction of the arrow in Fig. 1. y

Fig. 3 is asectional plan view, taken on the line 3-3 of Fig. 1.

Fig. 4 is a vertical-section view on the line 4-4 of Fig. 3, looking in the direction of the arrow; the scale being enlarged.

The lower portion or base ofthe 'carrier comprises the usual plate-engaging foot 5, with a standard 6 having a Xed bobbin-supporting stem 7 rising therefrom, and a parallel thread-guide upright 8. Uponthe stem 7 is rotatably mounted the bobbin spindle 10, having a fixed ratchet wheel 11 at its base 30 and above, the standard 6; the bobbin .12, indicatedin dotted outline, being tight upon the `rotatable spindle and the thread passing therefrom through guide eye 8a to sioning mechanism;

In my improved construction the base standard 6 is. formed with al tensioning` spring cylinder 15 arranged transversely of the bobbin spindle, and is provided with a tensioning lever 16 which is pivotally mount'- ed concentric with said cylinder and has a thread-engaging end portion 16a. As shown' this lever is formed with a fork-head `which spans the base standard 6, and its separated ,Y arms 16", 16b are pivotally mounted on the projecting ends of a bushing sleeve 17 in the cylinder 15, with the connected tensioning spring 20 in the latter operatingl to swing downward thethread-engaging end 16a of the lever; the normaltensioning ofV the spring being readily varied by means of a rotatable springengaged cap 21 having a pin 22 adapted to be set into engagement Y with one or another of a corresponding cir-V cular series of holes inthe adjacentlever arm 16",-the opposite end ofthe coiled the tcny YSaid lever.

r`which is also pivoteid concentric with the tensioni'ng-sprlng cylinder 15 and has its pawl arm125'c1 normally swung into engagement with the bobbin ratchet wheel llby a springpressed plunger device 26 bearing against lan opposlt-ely extending arm 25"; this pawl leverv being releasingly operated by the lifting of .the tensioning lever 16 when more thread is needed. As shown, the pawl lever 25 is pivotally mounted midway between the fork-head pivoting portions 16b of the tensioning lever 16, upon .the bushing sleeve 17 in the tensioning-spring cylinder, the latter being provided with a midway vertical slot to receive it; and it isM formedwith a lateralprojection or projections 25c so arranged as to contact with an operating offset or offsets 16c on the tensioning lever 16 when the latter is being fully raised by the pull of the thread. The lateral projections 161 on the tensioning lever merely serve to automatically operate a stop mechanism in case of thread breakage.

The preferred construction specifically set forth may obviously be readily `Y modified without departing delined in the claims.

What I claim is:

1. In a carrier having a rotatably mountedV ratchet-controlled bobbin; a carrier base having a cylindricalV tensioning-spring chamber arranged transversely of thev bobbin, a bobbin-engaging from the invention as pawlV lever .and Va thread-operated pawl-releasing lever both" `pivotally mounted concentric with said transverse spring chamber, and a tensioning springin said chamber operating upon said pawl-releasing lever. Y 2. .In a carrier having a rotatably mounted ratchetfcontrolled bobbin; a carrier base havling a cylindrical tensioning-spring .chamber Varranged transversely of the bob-V bin, a bobbin-engaging pawlY lever anda thread-Operated pawl-releasing lever both" pivotally mounted concentric with said transverse spring chamber, a spiral springV inv .Y said vchamber operatively connected to said pawl-releasing lever, anda spring-tensioning. chamber cap adj ustably engaging hin haring' a toot portion, a fixed Standard thereon the upper portion ot which forms a liohhiu vaipport and the intermediate portion oi whiih is formed `with a transversely arranged teiieioningspring eluunber. a bol)n liiilM-eleae'ing pawl lever pivotaily mounted eonrentrie with said traneverse chamber, a tensioning spring: mounted in Said elnnnher, and a tensioning lever also pivotally 1nounted concentric with said chamber and opertive upon said ):iwl lever under Control of said spring, said transverse chamber having n spring-enelosingr cylindrical bushing upon which both Said levers are pivotally mounted.

5. A carrier for rntelret-eolitrolled hohbin having a foot portion, a .tixed standard thereon the upper portion ot which if'ornis a hobbin support and the intermediate portion of which is torlned with a transversely arranged tenuimung-Spring ehaniher.` a hohhin-releasing pasvl lever pivotally mounted eoneentrie with said transverse chamber, a tensioning.;r spring nlounted in said eliainhe'r, and a tensioning lever also pivotally mounted concentric with said chamber und open ative upon said pawl lever under control of Suid spring, said transverse ehaniber having :i epringrnclosing cylindrical bushing, and

said pawl lever and tensioning; lever being pivotally mounted upon the midi'vay portion and end portion respectively of said bushing.

In testimony whereof I nix my signature.
